Specification of Letters l'atent.

Application filed March 16, 1911." Serial No. 614,915.

To all whom it may concern Be it known that I, ELMER JONES, a citizen of the United States, residing at Atlanta, in the'county of Fulton and 'State of Georgia, have invented'a certainnew and useful Improvement in Train-Controlling Devices, of which the following is a run, clear, and exact description, reference being had to the accompanying drawings. I This invention relates to traincontrolling devices adapted to be installed upon a locomotive or other moving vehicle and operated bymechanisin located alongthe track l lore particularly the invention provides mechanism so operated for releasing the air to apply the brake. I v The objects of the invention are'to provide' such mechanism in a form which shall be very eflicientand certainin operation, while'being simple and cheap in construction. i

The particularcharacteristics of themes.

ent invention are hereinafter more fully explained so that, for the present, the invention may be conveniently summarized as consisting of the combinations of cooperating elements explained herein" and summarized in the claims.

'In the drawings, Figure 1 is a sideelevation of my mechanism applied to a vehicle truck, portions of "the mechanism being broken away; this view showing also the co operating track trip. Fig. 2 is a plan of my air releasing device on the vehicle. I

Referring to the parts shown by numerals,1'represents the track; 2 a suitable trip or ramp adapted to be raised into posi tion to oooperatewith the air releasing de vice on the locomotive.

3 indicates a'lever adapted to be engaged by a member on the locomotive; 4 a rock shaft to which said lever is secured, and 5 another lever secured to said rock shaft, this latter lever OperatingPtoraise the ramp 2.

In normal position thelever .3 extends approximately vertically, and the ramp. 2 is below the path of the mechanism of the locomotive. When, however, a bumper of the locomotive strikes the lever 3, the arm 5 raises the ramp 2 into the position shown'in Fig. '1,which causes that ramp to become effective on theair controllingmechanism to be described. y i i 10in Fig.1representsthe frame ofthe illustration of any suitable stationary part ofthevehicl'e. Secured to this frame is a casting 11, having an open box-like portion, 12, which carries my air releasing'mechanism. The forward under portion of the casting 11 is shown as constituting the bumper which impinges the arm 3, and such impingement raises the ramp 2-into the slot 13 in the bottom of the vcasting. In

truck of the vehicle and is" to betaken as an I this position 'the'ramp may engage the airy p releasing mechanism, whichl will now descr1be.--

15in Figrlis the body of the air valve. I

Within this body is a chamber having a seat which is occupied-by the plug valve 16. On top of this valve is a spring, 17 and above the spring is a head, 18. Bearing on this head is an arm, 19, of a lever, which is loosely pivoted at 20 to ears',*21,projecting fromthe valve casing. After passing across the head 18, the lever arm, 19, at its free end is pivotally connected with a link, 22, to the lower end of which is pivotally secured bar, 23, which extends first downwardly, preferably in the are shown, and then diagonallyupwardly asshown at 24c, andvthen along substantially horizontally. [At its other end, the bar 23 is pivoted to a stationary pin, 26. Securedto the bar "23 near its pivoted end is an extension bar, 27, which, extending diagonallyupw'ard, has at its extreme end a'toe, 28, which is adapted tooverhang a toe, 29, on thelower end of an arm 30 on the lever 19. f j I From the construction described it will be seen that the lever .19 is normally, held down at each end,-the slot-'25 around the pin 20 preventing that portion normally acting to hold'the lever. The center line of the valve being-to theleft ofthe pivot point loo raised, engages the incline 2 1 of the bar 23,

that-bar will be swung on its pivot, causing throughthe passageways 36, thus applying upwardly under the air pressure into theposition shown in dotted lines. Thisreleases the air, which comes into the valve through the passageway 35, and allows it to escape the brake.

that all of the parts concerned in holding the valve closed are necessary for that action, so that if any of them should become broken, distorted or removed, the valve would automatically open and apply the brake. This is an important point, as it renders the device thoroughly reliable against tampering or accidents.

I provide at the top of ;the box 12 a resetting lever 40, which is shown as pivoted atel, normally held up by a spring 42 and provided with a plunger 43, adapted to bear downwardly on the arm 19. Accordingly, after the device has operated, the arm'19 comes into the position shown in dotted lines; to reset, it is only necessary to press downwardly on thelever 40. The slot in the ear 21, into which the pin 20 projects, limits the movementof the lever 19 so that it never gets out of re-setting bounds.

Having described my invention, what I claim is:

1. In a device ofthe character-described, the combination of a valve, a bodily movable. member for. holding it closed, means acting on saidmember on opposite sides of the valve for holding the member at two points either of which may move to release the valve, and means for efiecting such movement.

'2. In a mechanismof the class described, the combination with a valve of a bodily movable bar extending-across the valve and bearing. intermediately against it, a movable anchorage for each end of said bar, and means for releasing said bar when desired at one end.

3. In a device of the character described, the combination with a valve, of a member acting intermediately thereon to hold it closed, a movable holding device for said member on one side of the valve and a sepa-' rable latch for the member on the other side, one portion of which is connected with said movable holding" device, and means for releasing said latch by moving said holdingv device. 4c. Ina device of the character described, the combination with an air valve-of members normally connected in a circuit and actingon the valve to hold it closed, saidcircuit of members being pivoted-at one. point and being separable at another, and means for moving such parts on said' pivot.

V 5. In amechanism of the class described,
